Which squealing, scraping or thumping dryer noises need service?
Record whether the load explains the pattern
Describe whether the noise occurred with a bulky bundle, shoes or a normal load, and whether it began after moving the dryer. Preserve a safely recorded clip rather than running repeated test cycles. Persistent metal scraping, forceful movement, burning odor or visible damage should end use until assessed. An explanation that some operating sounds are normal does not establish that your new sound is harmless.
